i dont think it is completely useless and in this case. Look, I hate wash trades as well, but I'm looking at the list of trades and GIGL's finale does not look like a wash trade. Stock basically toggled before seeing trades in-between the (.045, .055) range.
99% of penny stocks are pump and dumps, yet 100% of penny stocks pretend to be in the 1%. Contracts, patents, mergers, partnerships, and other such news are usually "too good to be true" and should be looked at in detail. The source should also be vetted.
